Then you will be left with very few pins to work with . If you have multiple sensor or push buttons … you need to have different nodemcu for each sensor or button . This simply adds to the over all cost of the project. And even bulkier.
I read somewhere on the internet using a ATtiny 85 to keep buffer of 1sec on the output pins will prevent false latching due to short pulse on the boot up.
Anyone have idea on how to use this logic ?
